Abstract Sustainable fisheries management requires regular scientific monitoring of fish stocks. When information on certain stocks is limited, environmental DNA (eDNA) holds promise to complement traditional surveys. However, a better understanding how eDNA concentrations relate abundance and biomass needed. Here, quantification two commercially important flatfish species in the North‐East Atlantic, common sole ( Solea solea ) European plaice Pleuronectes platessa ), was assessed. First, species‐specific, probe‐based assays for targeting mitochondrial cytochrome b c oxidase subunit I gene, respectively, were developed (for sole) validated both species). Subsequently, mesocosm experiments revealed significant positive relationship between at three emission time periods (5 min, 1 h, 24 h).

Abstract A significant challenge in comparing and contrasting regional reviews of non-native marine species diversity is that evaluation methods vary widely, resulting highly inconsistent taxonomic, habitat historical coverage even ostensibly well-studied regions. It thus difficult to interpret whether strikingly different numbers regions reflect differential invasion patterns or assessment criteria capabilities. We provide a comprehensive guide the techniques assess timing history cryptogenic species. emphasize need broaden taxonomic breadth when documenting invasions, use broader deeper search term menu (including using older terms), thoroughly access global systematic literature for local, records, delve into avoid dates-of-publication tempo rates.

Abstract The coastline of Sub‐Saharan Africa hosts highly diverse fish communities great conservation value, which are also key resources for local livelihoods. However, many costal ecosystems threatened by overexploitation and their state is frequently unknown due to vast spatial extent limited monitoring budgets. Here, we evaluated the potential citizen science‐based eDNA surveys alleviate such chronic data deficiencies assessed in Mozambique using two 12S metabarcoding primer sets. Samples were either collected scientific personnel or trained community members results from primers combined a new merging approach. Irrespective background sampling personnel, high average species richness was recorded (38 ± 20 OTUs per sample). Individual sections largely differed occurrence commercially important species, highlighting need regionally differentiated management strategies. A detailed comparison applied sets revealed an trade‐off choice with MiFish amplifying higher number but Riaz performing better detection species. This could be partly resolved applying our data‐merging approach, especially designed increase robustness multiprimer assessments regions poor reference libraries. Overall, study provides encouraging highlights that eDNA‐based will require further improvements of, example, databases analytical infrastructure facilitate routine applications Africa.

Species detection using environmental DNA (eDNA) is a biomonitoring tool that can be widely applied to mangrove restoration and management. Compared traditional surveys are taxa-specific time-consuming, eDNA metabarcoding offers rapid, non-invasive cost-efficient method for monitoring biodiversity characterising the spatio-temporal distribution of multiple taxa simultaneously. General guidelines well-established aquatic systems, but habitat-specific still lacking. Mangrove habitats, as priority ecosystems in Southeast Asia, present unique prospects challenges these regards. Environmental used (1) track functional recovery ecological restoration, (2) prioritise conservation areas, (3) provide early warning threats, (4) monitor threatened taxa, (5) response climate change, (6) support community-based restoration. However, potential applications have yet been realized Asia due technical challenges, lack standardised methods, difficulties defining community, data limitations, funding, infrastructure capacity. Successful implementation activities would encourage development data-driven coastal management equitable programs. Eventually, this promote Asia’s shared regional interests food security, defence conservation.

Effective governance of the global ocean under accelerating environmental and social changes depends on sufficient scientific knowledge that unravels complexity dynamic marine ecosystems. In case vast remote twilight zone (OTZ), management is particularly challenged by lack data. Traditional biodiversity monitoring methods are unable to scale efficiently or effectively address these gaps new technologies needed inform policy. Environmental DNA (eDNA) has quickly gained traction in recent years as an enabling technology for conservation will play a transformative role OTZ high seas general. Through comprehensive review science policy literature analysis existing data, we discuss importance OTZ, gaps, summarize developments eDNA research.

Abstract Animal pollination is an important and highly valued ecosystem function the role of birds as pollinators increasingly acknowledged. However, such interactions can be challenging to document often require extensive field programs. Over last decade, environmental DNA (eDNA) has been analyzed from several different contemporary sample types, water, soil, flowers, air. The applications these studies include biodiversity monitoring, detection endangered species, community compositions, more recently, flower–arthropod interactions. it remains unknown whether flower eDNA applicable other taxonomic groups interacting with plants, well deposition degradation on flowers. Here, we test flowers used for detecting bird pollinators. In a controlled environment (an aviary great tits [ Parus major ]), show that leave significant traces without observed visits (airborne eDNA). We further when had in contact concentrations increased levels significantly higher than airborne background DNA. Subsequently, sampled five clusters wild Papua New Guinea detected four species birds, two which are nectar‐feeders, one insectivorous known visit These were regularly seen area caught mist‐nets days prior sampling total, 29 recorded (18 mist‐netted) these, eight nectarivorous. Our quantitative approach suggests possible distinguish deposited actual wild, although this might context‐specific. findings broad interest within research functioning, biotic interactions, plant–animal mutualism.
